摘　　要：通过西藏旁多水利枢纽灌溉输水洞水力学模型试验,对无压输水洞洞内消能及消能工优化展开了研究。结果表明,下挖式消力池能较好地解决无压输水洞洞内消能问题,同时,在满足消能防冲要求、确保工程安全的情况下,应尽量使消能工的体型简化,以利施工及运行后维护工作的进行。The paper studies the energy dissipation in inner for non-pressure conveyance tunnel and dissipator optimization by the hydraulic model of irrigation conveyance tunnel of Pangduo hydro-junction in Tibet.The result shows that the digging type stilling basin could solve the question of energy dissipation in inner for non-pressure conveyance tunnel well.The dissipator body type should be simplified for the construction and maintenance on the premise of meeting requirement and safety.
